Description

Technical Field

[0001] This utility model relates to the field of construction engineering cost technology, and more specifically to a construction engineering cost on-site surveying device. Background Technology

[0002] In engineering cost consulting activities, on-site inspection is an important part of project settlement review. This involves measurement, which requires the use of surveying equipment. Existing surveying equipment uses tripods for support, but the existing tripod technology has certain defects. The part that contacts the ground is a pointed tip. On soil or grass, the pointed tip can be inserted into the soil for stable positioning and support, but on flat surfaces such as concrete, the pointed tip has too small a contact area, resulting in insufficient support and easy displacement due to accidental contact. This requires readjustment, which greatly affects work efficiency. Utility Model Content

[0023] This utility model provides a construction engineering cost on-site surveying device, including a tripod and a machine head 12 detachably mounted on the upper end of the tripod. The tripod includes support rods 2, the lower ends of which are hinged to support components. A limiting component for locking the support components is provided between the support rods 2 and the support components. The tripod includes a base 1, the lower part of which is hinged to three support rods 2, with an angle of 120 degrees between the three support rods 2. The support components include a connecting plate 3, the lower end of which is fixedly connected to support feet 5, with an angle of 140 degrees to 170 degrees between the connecting plate 3 and the support feet 5. A soft pad 6 is fixedly connected to the lower surface of the support feet 5. The soft pad 6 is a sandbag filled with fine sand. The soft pad 6 includes several vertical... The poles and uprights are movably installed inside the support feet 5. The lower end of the uprights is fixedly connected to a rubber head. When the support feet 5 contact the ground, the rubber heads at the ends of several uprights will adhere to the ground. The support assembly also includes an anchoring screw 8, which is screwed into the end of the support feet 5. The limiting assembly includes a fixing block fixedly installed at the end of the support rod 2. A slide rail is provided at a position symmetrical to the fixing block at the end of the support rod 2, and a movable seat 9 is slidably connected to the slide rail. The connecting plate 3 is located between the fixing block and the movable seat 9. The limiting assembly also includes a tightening screw 4 that passes through the fixing block, the connecting plate 3 and the movable seat 9 in sequence. One end of the tightening screw 4 is engaged with a nut 10. The middle of the base 1 is provided with a through hole 11 for installing the machine head 12.

[0024] The first embodiment of this utility model is as follows:

[0025] A construction project cost surveying device includes a tripod, which includes a base 1. The base 1 has a through hole 11 in the middle for mounting a machine head 12. The machine head 12 has a blind hole at the bottom. During installation, the machine head 12 is placed on the base 1, and then the lead screw is moved upward from the bottom of the base 1 and screwed into the blind hole to perform the installation.

[0026] The lower part of the base 1 is hinged to three support rods 2, and the angle between the three support rods 2 is 120 degrees, so that the ends of the support rods 2 form an equilateral triangle structure on the ground, which has high stability.

[0027] The lower end of the support rod 2 is hinged to a support assembly, which includes a connecting plate 3. The lower end of the connecting plate 3 is fixedly connected to a support foot 5. The angle between the connecting plate 3 and the support foot 5 is 140 degrees to 170 degrees. The connecting plate 3 and the support rod 2 can rotate relative to each other to adjust their angle so that the lower surface of the support foot 5 is parallel to the ground. The limiting assembly includes a fixing block fixedly installed at the end of the support rod 2. A slide rail is provided at a position symmetrical to the fixing block at the end of the support rod 2, and a movable seat 9 is slidably connected to the slide rail. The connecting plate 3 is located between the fixing block and the movable seat 9. The limiting assembly also includes a tightening screw 4 that passes through the fixing block, the connecting plate 3 and the movable seat 9 in sequence. One end of the tightening screw 4 is engaged with a nut 10. In use, screwing in the nut 10 allows it to move along the tightening screw 4, thereby pushing the movable seat 9 toward the connecting plate 3. After contact, further tightening allows the fixing block, the connecting plate 3 and the movable seat 9 to be tightly pressed together and relatively fixed by friction.

[0028] When used on soft ground such as soil, the anchoring screw 8 can be used for fixation. The anchoring screw 8 is set at the end of the support foot 5 in a screw-in manner. The lower end of the anchoring screw 8 is provided with a tip 7, which makes it easier to insert into the soil. When using, place the support foot 5 on the ground, and then screw in the anchoring screw 8 to move it downward and insert it into the soil to complete the limiting fixation.

[0029] When used on hard, flat surfaces such as asphalt roads, a soft pad 6 can be used for positioning. The soft pad 6 is fixedly connected to the lower surface of the support foot 5. The soft pad 6 is a sandbag filled with fine sand. When using it, place the support foot 5 and the sandbag on the ground and then step on it to make the sandbag conform to the shape of the ground. At the same time, the sandbag is made of canvas, which has a large friction force, making it difficult for the support foot 5 to move on the ground, thereby improving stability.

[0030] In other embodiments, the pad 6 includes several uprights, each of which is movably disposed inside the support foot 5. The lower end of each upright is fixedly connected to a rubber head. When the support foot 5 contacts the ground, the rubber heads at the ends of the uprights will adhere to the ground. The rubber heads have high friction with the ground, making it difficult for the support foot 5 to move on the ground, thereby improving stability.

[0031] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0032] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
